Blackfriday [![Build Status](https://travis-ci.org/russross/blackfriday.svg?branch=master)](https://travis-ci.org/russross/blackfriday)
===========
Blackfriday is a [Markdown][1] processor implemented in [Go][2]. It
is paranoid about its input (so you can safely feed it user-supplied
data), it is fast, it supports common extensions (tables, smart
punctuation substitutions, etc.), and it is safe for all utf-8
(unicode) input.
HTML output is currently supported, along with Smartypants
extensions.
It started as a translation from C of [Sundown][3].
Installation
------------
Blackfriday is compatible with any modern Go release. With Go 1.7 and git
installed:
go get gopkg.in/russross/blackfriday.v2
will download, compile, and install the package into your `$GOPATH`
directory hierarchy. Alternatively, you can achieve the same if you
import it into a project:
import "gopkg.in/russross/blackfriday.v2"
and `go get` without parameters.
Versions
--------
Currently maintained and recommended version of Blackfriday is `v2`. It's being
developed on its own branch: https://github.com/russross/blackfriday/tree/v2 and the
documentation is available at
https://godoc.org/gopkg.in/russross/blackfriday.v2.
It is `go get`-able via via [gopkg.in][6] at `gopkg.in/russross/blackfriday.v2`,
but we highly recommend using package management tool like [dep][7] or
[Glide][8] and make use of semantic versioning. With package management you
should import `github.com/russross/blackfriday` and specify that you're using
version 2.0.0.
Version 2 offers a number of improvements over v1:
* Cleaned up API
* A separate call to [`Parse`][4], which produces an abstract syntax tree for
the document
* Latest bug fixes
* Flexibility to easily add your own rendering extensions
Potential drawbacks:
* Our benchmarks show v2 to be slightly slower than v1. Currently in the
ballpark of around 15%.
* API breakage. If you can't afford modifying your code to adhere to the new API
and don't care too much about the new features, v2 is probably not for you.
* Several bug fixes are trailing behind and still need to be forward-ported to
v2. See issue [#348](https://github.com/russross/blackfriday/issues/348) for
tracking.
Usage
-----
For the most sensible markdown processing, it is as simple as getting your input
into a byte slice and calling:
```go
output := blackfriday.Run(input)
```
Your input will be parsed and the output rendered with a set of most popular
extensions enabled. If you want the most basic feature set, corresponding with
the bare Markdown specification, use:
```go
output := blackfriday.Run(input, blackfriday.WithNoExtensions())
```
### Sanitize untrusted content
Blackfriday itself does nothing to protect against malicious content. If you are
dealing with user-supplied markdown, we recommend running Blackfriday's output
through HTML sanitizer such as [Bluemonday][5].
Here's an example of simple usage of Blackfriday together with Bluemonday:
```go
import (
"github.com/microcosm-cc/bluemonday"
"github.com/russross/blackfriday"
)
// ...
unsafe := blackfriday.Run(input)
html := bluemonday.UGCPolicy().SanitizeBytes(unsafe)
```
### Custom options
If you want to customize the set of options, use `blackfriday.WithExtensions`,
`blackfriday.WithRenderer` and `blackfriday.WithRefOverride`.
You can also check out `blackfriday-tool` for a more complete example
of how to use it. Download and install it using:
go get github.com/russross/blackfriday-tool
This is a simple command-line tool that allows you to process a
markdown file using a standalone program. You can also browse the
source directly on github if you are just looking for some example
code:
* <http://github.com/russross/blackfriday-tool>
Note that if you have not already done so, installing
`blackfriday-tool` will be sufficient to download and install
blackfriday in addition to the tool itself. The tool binary will be
installed in `$GOPATH/bin`. This is a statically-linked binary that
can be copied to wherever you need it without worrying about
dependencies and library versions.
Features
--------
All features of Sundown are supported, including:
* **Compatibility**. The Markdown v1.0.3 test suite passes with
the `--tidy` option. Without `--tidy`, the differences are
mostly in whitespace and entity escaping, where blackfriday is
more consistent and cleaner.
* **Common extensions**, including table support, fenced code
blocks, autolinks, strikethroughs, non-strict emphasis, etc.
* **Safety**. Blackfriday is paranoid when parsing, making it safe
to feed untrusted user input without fear of bad things
happening. The test suite stress tests this and there are no
known inputs that make it crash. If you find one, please let me
know and send me the input that does it.
NOTE: "safety" in this context means *runtime safety only*. In order to
protect yourself against JavaScript injection in untrusted content, see
[this example](https://github.com/russross/blackfriday#sanitize-untrusted-content).
* **Fast processing**. It is fast enough to render on-demand in
most web applications without having to cache the output.
* **Thread safety**. You can run multiple parsers in different
goroutines without ill effect. There is no dependence on global
shared state.
* **Minimal dependencies**. Blackfriday only depends on standard
library packages in Go. The source code is pretty
self-contained, so it is easy to add to any project, including
Google App Engine projects.
* **Standards compliant**. Output successfully validates using the
W3C validation tool for HTML 4.01 and XHTML 1.0 Transitional.
Extensions
----------
In addition to the standard markdown syntax, this package
implements the following extensions:
* **Intra-word emphasis supression**. The `_` character is
commonly used inside words when discussing code, so having
markdown interpret it as an emphasis command is usually the
wrong thing. Blackfriday lets you treat all emphasis markers as
normal characters when they occur inside a word.
* **Tables**. Tables can be created by drawing them in the input
using a simple syntax:
```
Name | Age
--------|------
Bob | 27
Alice | 23
```
* **Fenced code blocks**. In addition to the normal 4-space
indentation to mark code blocks, you can explicitly mark them
and supply a language (to make syntax highlighting simple). Just
mark it like this:
```go
func getTrue() bool {
return true
}
```
You can use 3 or more backticks to mark the beginning of the
block, and the same number to mark the end of the block.
* **Definition lists**. A simple definition list is made of a single-line
term followed by a colon and the definition for that term.
Cat
: Fluffy animal everyone likes
Internet
: Vector of transmission for pictures of cats
Terms must be separated from the previous definition by a blank line.
* **Footnotes**. A marker in the text that will become a superscript number;
a footnote definition that will be placed in a list of footnotes at the
end of the document. A footnote looks like this:
This is a footnote.[^1]
[^1]: the footnote text.
* **Autolinking**. Blackfriday can find URLs that have not been
explicitly marked as links and turn them into links.
* **Strikethrough**. Use two tildes (`~~`) to mark text that
should be crossed out.
* **Hard line breaks**. With this extension enabled newlines in the input
translate into line breaks in the output. This extension is off by default.
* **Smart quotes**. Smartypants-style punctuation substitution is
supported, turning normal double- and single-quote marks into
curly quotes, etc.
* **LaTeX-style dash parsing** is an additional option, where `--`
is translated into `&ndash;`, and `---` is translated into
`&mdash;`. This differs from most smartypants processors, which
turn a single hyphen into an ndash and a double hyphen into an
mdash.
* **Smart fractions**, where anything that looks like a fraction
is translated into suitable HTML (instead of just a few special
cases like most smartypant processors). For example, `4/5`
becomes `<sup>4</sup>&frasl;<sub>5</sub>`, which renders as
<sup>4</sup>&frasl;<sub>5</sub>.
Other renderers
---------------
Blackfriday is structured to allow alternative rendering engines. Here
are a few of note:
* [github_flavored_markdown](https://godoc.org/github.com/shurcooL/github_flavored_markdown):
provides a GitHub Flavored Markdown renderer with fenced code block
highlighting, clickable heading anchor links.
It's not customizable, and its goal is to produce HTML output
equivalent to the [GitHub Markdown API endpoint](https://developer.github.com/v3/markdown/#render-a-markdown-document-in-raw-mode),
except the rendering is performed locally.
* [markdownfmt](https://github.com/shurcooL/markdownfmt): like gofmt,
but for markdown.
* [LaTeX output](https://github.com/Ambrevar/Blackfriday-LaTeX):
renders output as LaTeX.
* [Blackfriday-Confluence](https://github.com/kentaro-m/blackfriday-confluence): provides a [Confluence Wiki Markup](https://confluence.atlassian.com/doc/confluence-wiki-markup-251003035.html) renderer.
Todo
----
* More unit testing
* Improve unicode support. It does not understand all unicode
rules (about what constitutes a letter, a punctuation symbol,
etc.), so it may fail to detect word boundaries correctly in
some instances. It is safe on all utf-8 input.

// Package blackfriday is a markdown processor.
//
// It translates plain text with simple formatting rules into an AST, which can
// then be further processed to HTML (provided by Blackfriday itself) or other
// formats (provided by the community).
//
// The simplest way to invoke Blackfriday is to call the Run function. It will
// take a text input and produce a text output in HTML (or other format).
//
// A slightly more sophisticated way to use Blackfriday is to create a Markdown
// processor and to call Parse, which returns a syntax tree for the input

// markdown documents. You can assign a custom renderer and set various options

// Link references

// The basic format is:
//
// [1]: http://www.google.com/ "Google"
// [2]: http://www.github.com/ "Github"
//
// Anywhere in the document, the reference can be linked by referring to its
// label, i.e., 1 and 2 in this example, as in:
//
// This library is hosted on [Github][2], a git hosting site.
//
// Actual footnotes as specified in Pandoc and supported by some other Markdown
// libraries such as php-markdown are also taken care of. They look like this:
//
// This sentence needs a bit of further explanation.[^note]
//
// [^note]: This is the explanation.
//
// Footnotes should be placed at the end of the document in an ordered list.
// Finally, there are inline footnotes such as:
//
// Inline footnotes^[Also supported.] provide a quick inline explanation,
// but are rendered at the bottom of the document.
//
// reference holds all information necessary for a reference-style links or
// footnotes.
//
// Consider this markdown with reference-style links:
//
// [link][ref]
//
// [ref]: /url/ "tooltip title"
//

Package sanitized_anchor_name provides a func to create sanitized anchor names.
Its logic can be reused by multiple packages to create interoperable anchor names

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
education, socio-economic status, nationality, personal appearance, race,
religion, or sexual identity and orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting Dan Buch at dan@meatballhat.com. All complaints will be
reviewed and investigated and will result in a response that is deemed necessary
and appropriate to the circumstances. The project team is obligated to maintain
confidentiality with regard to the reporter of an incident. Further details of
specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

[![GoDoc](https://godoc.org/github.com/urfave/cli?status.svg)](https://godoc.org/github.com/urfave/cli)
[![codebeat](https://codebeat.co/badges/0a8f30aa-f975-404b-b878-5fab3ae1cc5f)](https://codebeat.co/projects/github-com-urfave-cli)
[![Go Report Card](https://goreportcard.com/badge/urfave/cli)](https://goreportcard.com/report/urfave/cli)
[![codecov](https://codecov.io/gh/urfave/cli/branch/master/graph/badge.svg)](https://codecov.io/gh/urfave/cli)
cli is a simple, fast, and fun package for building command line apps in Go. The
goal is to enable developers to write fast and distributable command line
applications in an expressive way.
## Usage Documentation
Usage documentation exists for each major version. Don't know what version you're on? You're probably using the version from the `master` branch, which is currently `v2`.
- `v2` - [./docs/v2/manual.md](./docs/v2/manual.md)
- `v1` - [./docs/v1/manual.md](./docs/v1/manual.md)
## Installation
Make sure you have a working Go environment. Go version 1.11+ is supported. [See the install instructions for Go](http://golang.org/doc/install.html).
Go Modules are strongly recommended when using this package. [See the go blog guide on using Go Modules](https://blog.golang.org/using-go-modules).
### Using `v2` releases
```
$ GO111MODULE=on go get github.com/urfave/cli/v2
```
```go
...
import (
"github.com/urfave/cli/v2" // imports as package "cli"
)
...
```
### Using `v1` releases
```
$ GO111MODULE=on go get github.com/urfave/cli
```
```go
...
import (
"github.com/urfave/cli"
)
...
```
### GOPATH
Make sure your `PATH` includes the `$GOPATH/bin` directory so your commands can
be easily used:
```
export PATH=$PATH:$GOPATH/bin
```
### Supported platforms
cli is tested against multiple versions of Go on Linux, and against the latest
released version of Go on OS X and Windows. This project uses Github Actions for
builds. For more build info, please look at the [./.github/workflows/cli.yml](https://github.com/urfave/cli/blob/master/.github/workflows/cli.yml).

# Change Log
**ATTN**: This project uses [semantic versioning](http://semver.org/).
## 2.0.0 - (unreleased 2.x series)
### Added
- `NewStringSlice` and `NewIntSlice` for creating their related types
- `Float64SliceFlag` for unmarshaling a list of floats from the user
- `Context.Lineage` to get all contexts from current up to global
- `Context.LocalFlagNames` to get the flag names from *only* the current context
- `BoolFlag.Value` to handle both default-false and default-true
### Changed
- `Context.FlagNames` now returns all flags in the context lineage
- `Context.IsSet` now considers the full context lineage
### Removed
- the ability to specify `&StringSlice{...string}` or `&IntSlice{...int}`.
To migrate to the new API, you may choose to run [the migrator
(python) script](./cli-v1-to-v2).
- The optimistic reordering of arguments and flags introduced by
https://github.com/codegangsta/cli/pull/36. This behavior only worked when
all arguments appeared before all flags, but caused [weird issues with boolean
flags](https://github.com/codegangsta/cli/issues/103) and [reordering of the
arguments](https://github.com/codegangsta/cli/issues/355) when the user
attempted to mix flags and arguments. Given the trade-offs we removed support
for this reordering.
- adapter code for deprecated `Action` func signature
- deprecated `App.Author`, `App.Email`, and `Command.ShortName` fields
- All `Context.Global*` methods, as the non-global versions now traverse up
the context lineage automatically.
- `Context.Parent` method, as this is now available via `Context.Lineage`
- `BoolTFlag` and related code, as this is now available via `BoolFlag.Value`
## [Unreleased] - (1.x series)
### Added
### Changed
### Removed
### Fixed
### Deprecated
### Security
## [1.19.1] - 2016-11-21
### Fixed
- Fixes regression introduced in 1.19.0 where using an `ActionFunc` as
the `Action` for a command would cause it to error rather than calling the
function. Should not have a affected declarative cases using `func(c
*cli.Context) err)`.
- Shell completion now handles the case where the user specifies
`--generate-bash-completion` immediately after a flag that takes an argument.
Previously it call the application with `--generate-bash-completion` as the
flag value.
## [1.19.0] - 2016-11-19
### Added
- `FlagsByName` was added to make it easy to sort flags (e.g. `sort.Sort(cli.FlagsByName(app.Flags))`)
- A `Description` field was added to `App` for a more detailed description of
the application (similar to the existing `Description` field on `Command`)
- Flag type code generation via `go generate`
- Write to stderr and exit 1 if action returns non-nil error
- Added support for TOML to the `altsrc` loader
- `SkipArgReorder` was added to allow users to skip the argument reordering.
This is useful if you want to consider all "flags" after an argument as
arguments rather than flags (the default behavior of the stdlib `flag`
library). This is backported functionality from the [removal of the flag
reordering](https://github.com/urfave/cli/pull/398) in the unreleased version
2
- For formatted errors (those implementing `ErrorFormatter`), the errors will
be formatted during output. Compatible with `pkg/errors`.
### Changed
- Raise minimum tested/supported Go version to 1.2+
### Fixed
- Consider empty environment variables as set (previously environment variables
with the equivalent of `""` would be skipped rather than their value used).
- Return an error if the value in a given environment variable cannot be parsed
as the flag type. Previously these errors were silently swallowed.
- Print full error when an invalid flag is specified (which includes the invalid flag)
- `App.Writer` defaults to `stdout` when `nil`
- If no action is specified on a command or app, the help is now printed instead of `panic`ing
- `App.Metadata` is initialized automatically now (previously was `nil` unless initialized)
- Correctly show help message if `-h` is provided to a subcommand
- `context.(Global)IsSet` now respects environment variables. Previously it
would return `false` if a flag was specified in the environment rather than
as an argument
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
- `altsrc`s import paths were updated to use `gopkg.in/urfave/cli.v1`. This
fixes issues that occurred when `gopkg.in/urfave/cli.v1` was imported as well
as `altsrc` where Go would complain that the types didn't match
## [1.18.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user (backported)
## [1.18.0] - 2016-06-27
### Added
- `./runtests` test runner with coverage tracking by default
- testing on OS X
- testing on Windows
- `UintFlag`, `Uint64Flag`, and `Int64Flag` types and supporting code
### Changed
- Use spaces for alignment in help/usage output instead of tabs, making the
output alignment consistent regardless of tab width
### Fixed
- Printing of command aliases in help text
- Printing of visible flags for both struct and struct pointer flags
- Display the `help` subcommand when using `CommandCategories`
- No longer swallows `panic`s that occur within the `Action`s themselves when
detecting the signature of the `Action` field
## [1.17.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
## [1.17.0] - 2016-05-09
### Added
- Pluggable flag-level help text rendering via `cli.DefaultFlagStringFunc`
- `context.GlobalBoolT` was added as an analogue to `context.GlobalBool`
- Support for hiding commands by setting `Hidden: true` -- this will hide the
commands in help output
### Changed
- `Float64Flag`, `IntFlag`, and `DurationFlag` default values are no longer
quoted in help text output.
- All flag types now include `(default: {value})` strings following usage when a
default value can be (reasonably) detected.
- `IntSliceFlag` and `StringSliceFlag` usage strings are now more consistent
with non-slice flag types
- Apps now exit with a code of 3 if an unknown subcommand is specified
(previously they printed "No help topic for...", but still exited 0. This
makes it easier to script around apps built using `cli` since they can trust
that a 0 exit code indicated a successful execution.
- cleanups based on [Go Report Card
feedback](https://goreportcard.com/report/github.com/urfave/cli)
## [1.16.1] - 2016-08-28
### Fixed
- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
## [1.16.0] - 2016-05-02
### Added
- `Hidden` field on all flag struct types to omit from generated help text
### Changed
- `BashCompletionFlag` (`--enable-bash-completion`) is now omitted from
generated help text via the `Hidden` field
### Fixed
- handling of error values in `HandleAction` and `HandleExitCoder`
## [1.15.0] - 2016-04-30
### Added
- This file!
- Support for placeholders in flag usage strings
- `App.Metadata` map for arbitrary data/state management
- `Set` and `GlobalSet` methods on `*cli.Context` for altering values after
parsing.
- Support for nested lookup of dot-delimited keys in structures loaded from
YAML.
### Changed
- The `App.Action` and `Command.Action` now prefer a return signature of
`func(*cli.Context) error`, as defined by `cli.ActionFunc`. If a non-nil
`error` is returned, there may be two outcomes:
- If the error fulfills `cli.ExitCoder`, then `os.Exit` will be called
automatically
- Else the error is bubbled up and returned from `App.Run`
- Specifying an `Action` with the legacy return signature of
`func(*cli.Context)` will produce a deprecation message to stderr
- Specifying an `Action` that is not a `func` type will produce a non-zero exit
from `App.Run`
- Specifying an `Action` func that has an invalid (input) signature will
produce a non-zero exit from `App.Run`
### Deprecated
- <a name="deprecated-cli-app-runandexitonerror"></a>
`cli.App.RunAndExitOnError`, which should now be done by returning an error
that fulfills `cli.ExitCoder` to `cli.App.Run`.
- <a name="deprecated-cli-app-action-signature"></a> the legacy signature for
`cli.App.Action` of `func(*cli.Context)`, which should now have a return
signature of `func(*cli.Context) error`, as defined by `cli.ActionFunc`.
### Fixed
- Added missing `*cli.Context.GlobalFloat64` method
## [1.14.0] - 2016-04-03 (backfilled 2016-04-25)
### Added
- Codebeat badge
- Support for categorization via `CategorizedHelp` and `Categories` on app.
### Changed
- Use `filepath.Base` instead of `path.Base` in `Name` and `HelpName`.
### Fixed
- Ensure version is not shown in help text when `HideVersion` set.
## [1.13.0] - 2016-03-06 (backfilled 2016-04-25)
### Added
- YAML file input support.
- `NArg` method on context.
## [1.12.0] - 2016-02-17 (backfilled 2016-04-25)
### Added
- Custom usage error handling.
- Custom text support in `USAGE` section of help output.
- Improved help messages for empty strings.
- AppVeyor CI configuration.
### Changed

- De-duping and optimizations.
### Fixed

### Changed
- Use `path.Base` in `Name` and `HelpName`
- Export `GetName` on flag types.
### Fixed
- Flag parsing when skipping is enabled.
- Test output cleanup.
- Move completion check to account for empty input case.
## [1.11.0] - 2015-11-15 (backfilled 2016-04-25)
### Added

- Testing against `tip` in Travis CI config.
### Changed

### Fixed
- Removed redundant tests.
- Use correct example naming in tests.
## [1.10.2] - 2015-10-29 (backfilled 2016-04-25)
